There is a ton of information to cover, which I would be more than happy to do on a question answer basis. Once I finish the process I'll have time to sit down and write a few hundred pages, but for now please ask and I will respond.
The most important thing I found was that anyone can own and operate an ATM. (well you can't have a felony attached to you. federal banking laws prohibit a felon from operating or participating in the banking business.)
The business as far as I know from research, as I haven't placed my first machine yet, is that you find a processing company to handle your transactions, a location willing to let you place your ATM, buy an ATM, install the ATM, put YOUR cash in the ATM. (in that order)
There are franchise opportunities available, but most people that I spoke to already in the business say go it alone finding the processor that offers the highest payout to you.
